tcpdump run as root not as any other user

[Achilles_2]

Hi all,

I run tcpdump as root and work but not work as any other user. It doesn't work on HP-UX - I get
tcpdump: recv_ack: promisc_phys: Not owner

from tcpdump.

How to fix it?

Thanks
Alex

Hi Alex,

I think you have to be root on HP-UX to run tcpdump. Refer the following link:

http://www.tcpdump.org/tcpdump_man.html

manish.

Hi,
Basically you can add s or S bit to the executable file, but this may cause security problems.
The best way is to give root privileges for this command via sudo for all users.

Victor,

Your suggestion is to give root privileges for this command via sudo for all users. How do I do?

If you have sudo installed, you must edit /etc/sudoerrs file.

where can I get the source?

Hi, Alex

You run visudo and do something like this:
Host_Alias MAIN=yourhostname

Cmnd_Alias TCPD=/usr/local/bin/tcpdump

ALL MAIN=NOPASSWD:TCPD


Good Luck
